Osaka University researchers applied pressure to a material to induce a Lifshitz phase transition and, in a world-first, found a direct link between the Lifshitz transition and changes in the material’s thermoelectric properties. The ability of a thermoelectric material to produce electricity from waste heat was improved more than twofold. Understanding the effect of the […]

Northwestern University researchers are reporting that doping tin selenide with sodium boosts its performance as a thermoelectric material. The newly devised material produces a significantly greater amount of electricity than the undoped material, given the same amount of heat input. The researchers can confidently suggest the material pushes thermo electric technology closer to commercial usefulness. […]
